Marie Louise had always had an inclination to dreariness and, as a result of the deaths of her mother and her husband and her confinement, she became ill and melancholic. After a few months she recovered her senses and assumed the regency.
The news of Amalie's deteriorated mental condition triggered Marie Louise's melancholy. She secluded herself for days on and refused to receive visitors. Again she recovered, but from then on she became overly anxious for her only son's welfare.
